qprocessordetection.h: Fix detection of 32-bit ARMv8
This is more future-proof. It fixes the detection of 32-bit on ARMv8-A
processors since it uses the __ARM_ARCH macro that GCC and Clang
define. For MSVC, we use _M_ARM, which also contains the architecture
version. MSVC does not currently support ARMv8 code, but when it does,
this commit should make the support automatic.
I don't know which compiler defines __TARGET_ARM_ARCH, but support it
too.
